Gas pipeline velocity and sound pressure level

Gas pipeline velocity and sound pressure level

Gas pipeline velocity and sound pressure level

(OP)
Hello,

I have a gas pipe orifice metering tube that measures 6 in OD schedule 40 with a 3.6 in orifice. I calculate velocities at the orifice around 163 Ft/sec.

Does anyone have a correlation on what sound pressure level that might produce?

Are there limits for erosion?

Thanks
Ken

RE: Gas pipeline velocity and sound pressure level

You could try the "Reduced-Noise Gas Flow Design Guide" published by NASA Glenn Research Center. I think it was preared by Nelson Acoustical Engineering, Inc. Texas.

I was able to down load a copy from the NASA website, it about 17MB.
